Equipment description
The equipment consists of an indoor unit and an outdoor unit air conditioning system. The
system produces heating or cooling as required.
The system can be powered in several ways.
•By DC solar alone. It will start up and run on just the solar
•By DC solar and a small amount of AC 240 Volt power.
•By AC 240 volt only. This would be applicable at night.
Installation is the same as a standard split system air conditioner with the addition of Solar
PV modules to supply the DC input.
The system is controlled by an optical remote control.
